UPDATE: Anna Paquin and Stephen Moyer get married!

Us Magazine reports that True Blood costars Anna Paquin and Stephen Moyer were married this evening at a private residence in Malibu, California. The couple were married beneath a tent across the street from the beach. Guests at the ceremony included actor Elijah Wood, True Blood creator Alan Ball, and costars Ryan Kwanten, Rutina Wesley, and Carrie Preston with husband Michael Emerson of Lost. Many carried wedding gifts in purple boxes with purple bows.

Paquin, with her hair in an updo, wore a white halter-neck gown for the sunset ceremony, and Moyer wore a dark suit.

"It was a beautiful evening to get married and the sunset was gorgeous. Anna and Stephen seemed very excited to celebrate their wedding day," a source told People.

The couple met and fell in love early on the set of HBO's hit supernatural saga, but kept their relationship private until February 2009. The couple announced their engagement last August but discussed little about their wedding plans.

This is Paquin and Moyer's first marriage, though Moyer has son Billy and daughter Lilac from previous relationships.
